2 Peter 1:1
Simeon Peter, a servant and apostle of Jesus Christ,
To those who have obtained a faith of equal standing with ours
by the righteousness of our God and Savior Jesus Christ:
There is literally nothing stated regarding the need to repent first.
In fact, it is the opposite.
The elect obtained faith by "the righteousness" of God the Son, Jesus Christ.
2 Peter 1:1 - KJV – Simon Peter, a servant and an apostle of Jesus Christ,
to them that have obtained like precious faith with us
through the righteousness of God and our Saviour Jesus Christ:
2 Peter 1:1 - BYZ –
συμεων πετρος δουλος και αποστολος ιησου χριστου
Simon Peter, servant and apostle of Jesus Christ
τοις ισοτιμον ημιν λαχουσιν
to those equal in honor to us having obtained by lot
πιστιν εν δικαιοσυνη του θεου ημων και σωτηρος ιησου χριστου
faith in Righteousness of the God of us and Savior Jesus Christ.
So what the Greek tells us is not what translators tell us which is what you tell us -
eg That this faith is
BY the righteousness of our God and Savior Jesus Christ...
Instead, the text states that this faith is
IN the Righteousness of our God and Savior Jesus Christ...
The IN here is not the IN otherwise translated as IN in much of Englishdom - That IN is from EIS, not EN...
So if you have faith IN God, you have faith EIS God, faith INTO God...
Showing movement into, and such faith moves its possessor into God, which means 'is acceptable to God'...
But here, EN is used, and it designates location - eg "within"...
So that it states that by lot they have received faith within the Righteousness of Christ...
Which argues somewhat in favor of your understanding, fwiw...
Yet more broadly, this indicates the Gift of God that Apostolic Faith can be and is...
